• Merge the XML document in a table

  Hello
  I want to merge some of the values of an xml document in a table "Project_Table".

  Any ideas how to change the procedure, in order to merge the data in the xml document in the table?
  
  Thank you

  Hello

  Here's what you need in your USING clause:

  SELECT to_number(extractvalue(column_value, 'task/@id'))                as task_id,
         to_date(extractvalue(column_value, 'task/@start'), 'YYYY-MM-DD') as start_date,
         extractvalue(column_value, 'task/@name')                         as task_name
  FROM TABLE(
    XMLSEQUENCE(
      EXTRACT(xmltype(v_clob), '//task')
    )
  )
  

  Since you want nodes "task" request, just extract them directly. In addition, 'id', 'start', 'name' is attributes, you must access them with an '@'.

  You can also take a look at function XMLTABLE (which tends to replace construction TABLE (XMLSEQUENCE (...))):

  SELECT *
  FROM XMLTABLE(
   '//task'
   passing xmltype(v_clob)
   columns task_id    number(15)    path '/task/@id',
           start_date date          path '/task/@start',
           task_name  varchar2(100) path '/task/@name'
  )
  

  Edit: the XMLType constructor overload taking a BFILE type as an argument, so you can simplify the code a bit more:

  DECLARE
  
   v_xml XMLTYPE := XMLTYPE( BFILENAME('DTEMP', 'test.xml'), nls_charset_id('AL32UTF8') );
  
  BEGIN
  
  MERGE INTO project_table t
  USING (
    SELECT *
    FROM XMLTABLE(
     '//task'
     passing v_xml
     columns task_id    number(15)    path '/task/@id',
             start_date date          path '/task/@start',
             task_name  varchar2(100) path '/task/@name'
    )
  ) r
  ON (t.task_id = r.task_id)
  WHEN MATCHED THEN ...
  WHEN NOT MATCHED THEN ...
  ;
  
  ...
  
  END;

• Alteration of the content of an XML node in java

  Hi all
  
  I change the contents of an XML node using java, using the method of setTextContent() a node.
  
  Sometimes I also add child nodes of a node. In this case, when I add the child nodes of a given node, when I print the xml data, I see the added nodes.
  
  for example:
  
  Initial XML:
  
  < a > < / a >
  < b > < / b >
  < c > < / c >
  
  
  For my project requirement, based on certain conditions, I do 'a' 'b', 'c' as children nodes nodes. I reached this output.
  
  
  The problem is
  
  FINAL XML:
  
  < a > < b > < / b > < c > < / c > < / a >
  
  
  I get the nodes children in the same line as above. But the power required should be as below.
  
  
  REQUIRED XML
  
  < a >
  < b > < / b >
  < c > < / c >
  < /a >
  
  I also used the Doc.normalize () function. But still, it helps strength.
  
  Kindly help me in this regard.

• Create an xml file using the .xsd file

  Hi guys,.

  Version of DB: Oracle 11g

  I was wondering if I had any package that can create a xml file based on a (built-in) .xsd file. I searched but did not find any resource on the internet specific to my problem. Let's say I have an .xsd file. It is possible to load a schema and generate the XML that conform to the .xsd file using sql? If so, I want to store in a CLOB variable.

  Please point me to the right direction.

  Thank you.

• Can we change the name of the XSD/XML in Bpel node

  Hello
  
  I have here is the structure of the xsd that I created and captured the XML in it, in my Bpel process flow:
  
  nodes <>
  < NodeFirst >
  < NodeSecond >
  < / node >
  
  While he will send customer, I need to rename nodes as:
  
  nodes <>
  * < node / > *.
  * < node / > *.
  < / node >
  
  The names of the two nodes must be changed to "Namesake" in XML Final.
  
  Is it possible that we can do this, appreciate any help on this.
  
  Thank you
  Puneet

  It means that you must create a xsl map in which you "create" the exact names and fill them with data from the 'old' elementnames.
  in this case the transformation will do the same if you rename the element

  or use bpelx:rename

• generate the xsd file xml data

  I would like to make my java application automatically convert a given to a one .xml .xsd file.
  I know that with jdev, you can generate an xsd one xml file, and I want my application to do the same thing.
  I also know that I can use JAXB: first of all, I bind the xsd file, then I marshall the java class created for the xml. But I don't know how to do it.
  y at - it a simple way to use the 'things' behind the generation of xml xsd jdev.

• XML validation against the XSD schema

  Hi all
  
  I have a strange problem.
  
  I'm trying to validate an XMLTYPE variable against a XSD schema using the XMLisValid function.
  
  The XML code that I am trying to validate returned false (0) when you use this method.
  
  However, when I save the XSD against a column in a table, and then insert this XMLTYPE in this column, I don't get any errors. If I change the XSD to ensure failure when using this method, I get an error, if it is registered and work.
  
  I then created a very basic XSD and both methods work when validating XML against that. Then of course the XSD harder I want to validate against a difference, but I expect or them both don't both pass, not a failure and a single pass.
  
  Does anyone know why it would return different results?
  
  Thanks in advance for your help.

  Just had a quick glance at your XSD complex...

  You have a piece of 'delete' that is required as part of the sequence of elements with the element "centers." Yet your XML will fail validation compared with what it has only one item "add".

  Maybe your

  Just guessing. ;)

• How to create the default column in XML schema?

  Hi all
  
  I would like to define a default column Let's say Run_Date as Date data type in XML (XSD) schema definition and would fill column Run_Date SYSDATE, when XML documents are parsed to this schema.
  Let me know, how can we achieve?
  
  Thanks in advance.

  Also, I can not change the contents of the XML file, because it is generated by another language, but I can change the definition of XML schema, if necessary.

  Well, if you can not change the XML instance, you cannot change the schema, it conforms to the.
  You can add an optional attribute whose value by default, but we can only use a static value.

  How do you insert the file into the table?

• If you programmatically, via an INSERT statement, then I think your best bet is to create a new table with a relational schema XMLType column and a DATE column:

  CREATE TABLE employees (
    dt_created date default sysdate not null
  , xmldoc     xmltype
  , CONSTRAINT emp_pk PRIMARY KEY (xmldoc."XMLDATA".EMP_NO)
  )
  XMLTYPE COLUMN xmldoc STORE AS OBJECT RELATIONAL
  XMLSCHEMA "EMP.xsd" ELEMENT "Emp" ;
  

  If you choose to do so, remove the XML schema and enter it again with "genTables-online false."

• If you have inserted the file via the XDB (FTP, WebDAV, createResource) repository and relying on the table by default feature, then you may be out of luck.
  There is probably a way to tamper with the underlying structure of GOLD among a hidden column do accept a default value, but since it is not supported I won't even try.

• What to put in the xsd schema for the form of the ADF radio buttons?

  Hello, we create a form generated from the data of a HT ADF auto which is a type defined in a schema .xsd. Which schema component Let's in the .xsd schema correspond to buttons option in the form of the ADF? For example, in our .xsd we just

  <? XML version = "1.0" encoding = "UTF-8"? >

  " < xsd: Schema container = ' http://www.w3.org/2001/XMLSchema "xmlns:wf =" " http://www.example.org "

  " targetNamespace = ' http://www.example.org "elementFormDefault ="qualified"> "

  < xsd: complexType name = "FormDataType" >

  < xsd: SEQUENCE >

  < xsd: element name = "FirstName" type = "xsd: String" / >

  < xsd: element name = "Name" type = "xsd: String" / >

  < xsd: element name = "Department" type = "xsd: String" / >

  < / xsd: SEQUENCE >

  < / xsd: complexType >

  < / xsd: Schema >

  What would be the element / type etc be for radio buttons?

  Hi Tali,

  It depends on what you want to do with radio buttons, but it would be better to be a part of string in most cases.

  This could be better handled on the ADF OTN forum, but I'll take a shot at it.  If you have many items to choose from, you can use the string "Department", you already have in your XSD.  When displayed on the form, include various departments with radio buttons next to each other (for example,"manufacturing", "Marketing", "Sales").

  Because this is the BPM forum, I guess your XSD is used as data for a human task which in turn used to create a form of the ADF.  If this is the case, you can use your "Department" in your XSD string element that has already been placed on your form as a text input field.  The reason is the link that you need to update the element of the human task service is automatically created in this way.  Select this field to text, and then in the properties panel, copy the text that is in the 'value' of the field (you stick it in the Value property of the Radio group you will add in the next step).

  There are two ways to get the radio buttons on the form.  You might drag the "Radio group" widget on the form-> click on radio to 'Create a list (select an item)' button-> click the Add icon to add the choices you want to appear on the form (for example,' manufacturing ', 'Marketing', 'Sale').   Once this was added, paste property value text you copied in the previous step into the field of "Value" property of the new Radio group.

  If you select the radio button of the new group source, it should look like this if you wanted two choices for your radio buttons:

  After this has been added, delete the existing text entry field that was created when the form was generated automatically from the human task.

  Hope this helps,

• How to read the data with different XML schemas within the unique connection?

  • I have Oracle database 11g
  • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
  • I have several tables, each has an XMLType column, all based on patterns.
  • There are three XML schemas different registered in the DB
  • Maybe I need to read the XML data in multiple tables.
  • If all the XMLTypes have the same XML schema, there is no problem,
  • If patterns are different, the second reading will throw BindXMLException.
  • If I reset the connection between the readings of the XMLType column with different schemas, it works.

  The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

  Code to get data from XMLType is the implementation of case study:

   1   ResultSet resultSet = statement.executeQuery( sql ) ; 
   2   String result = null ; 
   3    while(resultSet.next()) { 
   4   SQLXML sqlxml = resultSet.getSQLXML(1) ; 
   5   result = sqlxml.getString() ; 
   6   sqlxml.free(); 
   7   } 
   8   resultSet.close(); 
   9    return result ; 
  

  It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

   1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
  

  Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

• Why xmlindex is not used in the slow queries on xml binary table eval?

  I run a slow simple query on Oracle 11.2.0.1 database server that does not use a xmlindex. Instead, a full table scan against the table eval binary xml occurs. This is the query:
  

   select -- /*+ NO_XMLINDEX_REWRITE no_parallel(eval)*/
        defid from eval,
        XMLTable(XMLNAMESPACES(DEFAULT 'http://www.cigna.com/acme/domains/eval/2010/03',
        'http://www.cigna.com/acme/domains/derived/fact/2010/03' AS "ns7"),
        '$doc/eval/derivedFacts/ns7:derivedFact' passing eval.object_value as "doc" columns defid varchar2(100) path 'ns7:defId'
         ) eval_xml
  where eval_xml.defid in ('59543','55208'); 

  The predicate is not selective at all - the number of rows returned is the same as the number of rows in table (325 550 in the eval table xml documents). When different values are used, which brings the number of lines down to ~ 33%, the xmlindex still is not used - as is expected in a purely relational XML environment.
  
  My question is why would'nt the xmlindex be used somehow full scan compared to a sweep of full table that cross the xml for each record in paper table eval?
  FFS suspicion would apply to a field of type xmlindex index?
  
  Here is the definition of xmlindex:

  XMLIndex definition is not correct, for the following reasons:

  In the COLUMNS clause, the path expression is compared to the context from the main event of XQuery item (HERE "/ eval").
  If you use an initial slash as you did, this indicates that the context item is an element of "derivedFacts" (which is not correct since it is an "eval" element).
  Therefore, the path points to no existing node:

  derivedFact XMLTYPE path ''/derivedFacts/ns7:derivedFact'' virtual
  

  There is a mismatch between the statements of prefix ns7, probably a typing mistake?

  ''http://www.cigna.com/acme/domains/derived/fact/2010/03'' AS "ns7"
  ...
  ''http://www.cigna.com/acme/domains/derived/FACT/2010/03'' AS "ns7"
  

  What "eval_xml" is referring to here?

  passing eval_xml.derivedFact
  

  The path to "defId" don't go too:

  defId VARCHAR2(100) path ''/derivedFacts/ns7:derivedFact/ns7:defId''
  

  Try this one, it should help you to:

  CREATE INDEX "EVAL_XMLINDEX_IX" ON "EVAL" (OBJECT_VALUE)
  INDEXTYPE IS "XDB"."XMLINDEX" PARAMETERS (
  'XMLTable eval_idx_tab_I
    XMLNamespaces(''http://www.cigna.com/acme/domains/derived/fact/2010/03'' AS "ns7",

    ''/eval''

• Get the XSD of the report query

  APEX 4.0.2
  Oracle 11.2.0.1.0
  
  Hello
  We are trying to retrieve the XML schema for a report query.
  
  The following code example works, but the "xsd" for p_document_format parameter is not documented.
  
  Is "xsd" a taken parameter value supported for APEX_UTIL. GET_PRINT_DOCUMENT?
  
  

  v_blob := APEX_UTIL.GET_PRINT_DOCUMENT (
      p_application_id      => NV('APP_ID'),
      p_report_query_name   => 'test', 
      p_report_layout_name => null,
      p_report_layout_type => null,  
      p_document_format     => 'xsd',
      p_print_server => null);

  Thank you in advance!

  Hi Eric,.

  We have four different versions of apex_util.get_print_document, so depending on what you want to do, you can create PDF files and other types of documents based on your own style, your own XML data sheets or pre-defined SEO report queries SQL with predefined, or in custom arrangements. We support the output formats, as I listed previously for the four releases. However, the internal implementation of these APIs is different for the API that refer to report queries and those that refer to custom XML data. When you reference the report queries, APEX of the first loading and running queries and generates XML data and then passes the XML the print rendering engine. The analysis and execution of these queries can use the same internal functions that are also used on the edition of report request page, where you have buttons which allow to have downloaded representations XML and the XML schema for the query for your report. XML and XSD documents are intended for use with the plug-in of BI Publisher Word or design tools XSL of third parties to design presentations. Now as the same internal functions are used, you can actually generate documents from XML Schema (XSD) using the apex_util.get_print_document API, but only with versions that allow you to refer to a report query predefined. This is not officially supported, I can assure you that this behavior will not change in the future, but I don't see why we would change that. The main reason to support XML in APIs is really to test the printing functionality without requiring a print rendering engine. But it seems that there are other cases of use for those both output formats.

  Hope the helps

  Kind regards

• Schema validation fails on the transformed XML document

  OK, this is weird.
  
  I get XML files that are supposed to conform to a given XSD. There are dozens of different parties who send these files. To be more precise, I refer to the Ontario Energy Board (OEB) PIPE Documents.
  
  I found that at least one sender sends invalid files. I can't that fixes to the source, so I'm working around that.
  
  for example

  <?xml version="1.0" encoding="UTF-8"?>
  <PIPEDocument  xmlns="http://www.oeb.gov.on.ca" 
                            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                            xsi:schemaLocation="http://www.oeb.gov.on.ca/ PIPEDocument.xsd" 
                            Version="4.0" 
                            DocumentReferenceNumber="xxx" CreationDate="20110825100008000ES">
  <MarketParticipantDirectory>
  <Sender>
  ...

  Oracle is not like this:
  

  ORA-31154: invalid XML document
  ORA-19202: Error occurred in XML processing
  LSX-00344: namespace values "http://www.oeb.gov.on.ca" and "http://www.oeb.gov.on.ca/" differ

  OK, so to work around this problem, before schema validation, I apply an XSLT transformation to clean the top-level element:
  

  <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.oeb.gov.on.ca">
  <xsl:output method="xml" indent="no"/>
  
  <xsl:template match="/">
      <xsl:copy>
        <xsl:apply-templates/>
      </xsl:copy>
  </xsl:template>
  
  <xsl:template match="*">
      <xsl:if test="local-name() = name()">
              <xsl:element name="{local-name()}">
                <xsl:apply-templates select="@*|node()"/>
              </xsl:element>
      </xsl:if>
  </xsl:template>
  
  <xsl:template match="@*">
      <xsl:if test="local-name() = name()">
              <xsl:attribute name="{local-name()}">
                <xsl:value-of select="."/>
              </xsl:attribute>
      </xsl:if>
  </xsl:template>
  </xsl:stylesheet>

  Nice: the fact that it is intended for:
  

  <?xml version="1.0" encoding="UTF-8"?>
  <PIPEDocument xmlns="http://www.oeb.gov.on.ca" 
                           Version="4.0" 
                           DocumentReferenceNumber="50520110825080908VA0001.EBT" 
                           CreationDate="20110825100008000ES">

  If I now the schema validate the above transformed XML, then it validates OK.
  
  Large? No, if I try to turn on the fly (i.e. without first transformation and followed by reading in the transformed data from the file), I get a strange error:
  

  declare
   v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML());
   v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; 
  begin
  if v_xml.isSchemaValid(v_xsd_name) = 1 then 
         dbms_Output.put_line('valid');
      else
         dbms_Output.put_line('invalid');
         
         --in order to get specific error info for a non-schema message need to convert the XML to schema based
         
         v_xml := v_xml.createSchemaBasedXML(v_xsd_name);
        
         v_xml.schemaValidate();               
         
      end if;  
  end;
  /

  ORA-31043: Element '' not globally defined in schema ''

  Exsqueeze me? What element in the schema?
  
  The transformation itself works very well. Specifically, if I run the following:
  

  select xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML()).getclobval() from dual;

  ... I get the desired result. Of course, if I save the result file and validate the fact that it works:
  

  declare
   v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604_manually_saved.xml'), 0);
   v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; 
  begin
  if v_xml.isSchemaValid(v_xsd_name) = 1 then 
         dbms_Output.put_line('valid');
      else
         dbms_Output.put_line('invalid');
         
         --in order to get specific error info for a non-schema message need to convert the XML to schema based
         
         v_xml := v_xml.createSchemaBasedXML(v_xsd_name);
        
         v_xml.schemaValidate();               
         
      end if;  
  end;
  /

  I would like to join example XML file, but it contains customer data so I can't do that. I would fix the XSD but it is the nest of a rat of 50 XSD with includes and a 300 script online registration scheme, so I can't do that.
  
  What I'm missing here?
  
  Looks like an Oracle bug for me at this isSchemaValid binds to a beginning of the XML instance and not to the instance transformed.
  
  thoughts?

  Hello

  Looks like an Oracle bug for me at this isSchemaValid binds to a beginning of the XML instance and not to the instance transformed.

  That wouldn't be surprising. There are "few" bugs on the XSL transformation.
  Here's a recently posted: {: identifier of the thread = 2245703}

  The solution was to serialize the output and analyze again.
  So, what you describe on 'reading of a works file' makes me think it's the same kind of problem.

  You can also view the contents of the variable just after that:

  v_xml := v_xml.createSchemaBasedXML(v_xsd_name);
